Finally, I'm getting around to changing the custom buttons. I found a couple of videos, but nothing 100% definitive for the Mavic 2 Pro. Obviously, the options are different for different Mavic drones. Here are the options for the Mavic 2 Pro:

C1 and C2 buttons have quite a few more options than the 5D button, so, it makes sense to use C1 or C2 for options that are not available on the 5D button.
That said, these are the settings I'm planning to use for everyday flying.
C1 = Center Auto Focus
C2 = Battery Info
5D Upper = Increase Exposure
5D Lower = Decrease Exposure
5D Left = AE Lock/Unlock
5D Right = Camera Forward/Down
I'm curious what others are using?
